Zamac Hammer-Screw
™
Nail Anchor
Product deScriPtion
The Zamac Hammer-Screw is a unique, one-step nail drive anchor featuring a Phillips type head
and a screw thread for use in concrete, block, brick or stone. It is available in 1/4" diameter and
lengths ranging from 3/4" to 3". With a body formed from corrosion resistant Zamac alloy and a
zinc plated carbon steel or Perma-Seal
™
coated drive screw, this anchor has been developed as an
improvement over standard nailin anchors.
The Zamac Hammer-Screw has been designed to provide a removable anchor with higher tension
load capacities compared with traditional nailin when installed in concrete. The anchor is not
recommended for overhead, life-safety or sustained tensile loading applications unless special
considerations are given to the allowable loads (see performance data section).

Installation Guidelines
1. Drill a hole into the base material to a depth of
at least 1/4” deeper than the required embedment.
The tolerances of the drill bit used should meet the
requirements of ANSI Standard B212.15.
Blow the hole clean of dust and other material.
2. Insert the anchor through the fixture. Drive the
screw into the anchor body to expand it. Be sure the
head is seated firmly against the fixture and that the
anchor is at the proper embedment. Take care not to
overdrive.
Optional: To remove – Press a Phillips screw driver
firmly into the screw head and turn counterclockwise.
Remove the screw from the anchor body, then pry
out the fixture and anchor body simultaneously by
working the claw of a hammer under the fixture
